A domestic engine manufacturer recently announced the official mass production of its new generation of high-efficiency air-cooled engines. Addressing the issues of uneven heat dissipation and high energy consumption in traditional air-cooled engines, this engine features an optimized heat sink structure design, employing a combination of high-density fins and airflow ducts, improving heat dissipation efficiency by 25%. It also incorporates an intelligent fuel injection system, reducing fuel consumption by 15% per 100 kilometers compared to traditional models, and meets the China VI b emission standards. Currently, the engine has passed 1000 hours of bench testing, achieving a reliability of 99.2%. Initial orders cover motorcycles and small agricultural machinery, with a monthly production capacity of 8000 units. Furthermore, this air-cooled engine has simplified its structural design, reducing the number of parts by 20%, thus lowering maintenance costs. The company's technical director stated that the next step will be to launch a high-altitude adapted version for plateau regions, optimizing the intake system to adapt to low-pressure environments. It is projected that sales of this series of engines will exceed 300 million yuan this year, contributing to the green upgrading of small and medium-sized machinery.
